Abstract: PURPOSE:To obtain a low-cost boron diffusing source having excellent shelf stability and reproducibility of a diffusion and capable of forming a film having high purity by a reaction product acquired by reacting boric acid ester and polyvinyl acetate in the presence of a solvent and an acid catalyst. CONSTITUTION:A boron diffusing source is manufactured by reacting a boric acid ester and polyvinyl acetate in the presence of a solvent and an acid catalyst. Said reaction is conducted in such a manner that a solution, in which polyvinyl acetate is dissolved in a solvent, and boric acid ester are mixed uniformly under agitation, the acid catalyst is added and a mixture is heated. It is favorable that 0.3-1mol alkyl borate is used to the 2mol acetyl oxy group of polyvinyl acetate at the mixing ratio of polyvinyl acetate and boric acid ester at that time. A reaction temperature is normally 40-150 deg.C, preferably 60-120 deg.C. A reaction time differs depending on the acid strength of the acid catalyst and loadings, but it is approximately 5-72hr.

Filed: 1988-08-10
Abstract: PURPOSE:To manufacture a thin oxide film excellent in superconductivity at a temp. lower than heretofore by executing sputtering of oxide superconducting material by using an ozone-containing gas. CONSTITUTION:An ozonizer is added to an RF magnetron sputtering device. Ar gas introduced through variable leak valves 9 is formed into plasmic state by means of the electric field of a high-tension electric power source 4. The generated electrons start performing a spiral motion by means of the electric field and the magnetic fields of magnets 12, by which ions Ar<+> are produced with high efficiency. The Ar ions are allowed to collide with a target 1 composed, e.g., of a sintered compact of Y-Ba-Cu-O-type compound oxide and sputter the target 1, by which an oxide superconducting material is deposited on a substrate 2. Further, an oxygen gas 7 is introduced via an ozonizer 8 into a vacuum chamber 15, and ozone is mixed with sputtering gas. By this method, sufficient oxygen can be supplied onto the substrate 2 surface by means of the decomposition of ozone, and the formation of oxide crystals can be facilitated.

Abstract: PROBLEM TO BE SOLVED: To suitably maintain a hot water temperature without influence of a heat insulation environment of a bathtub and to perform an energy conservation by setting next time waiting time after circulation heating based on a previous time waiting time of no circulation heating. SOLUTION: In the case of judging arrival of a bathtub hot water temperature tf after heating at a set temperature ts on the way of circulating and heating, burning of a bath burner is stopped, and next time waiting time Ts is calculated. The time Ts is calculated by Ts=Ts×n-(tf2-tf1-0.5)×10. The term (Ts×n) is a time required to judge necessity of circulating and heating. The term ((tf2-tf1-0.5)×10) indicates a correction term applied to the first term, and the correction term is to decrease the next time waiting time Ts for correction by considering a heat insulation environment in which the larger the difference between the set temperature ts and the temperature tf1 before circulating and heating, the more easily the environment is cooled.

Abstract: PROBLEM TO BE SOLVED: To enhance measurement accuracy for a temperature and a position and shorten a measurement time by setting a plurality of light sources of pulse lights thereby increasing an intensity of pulse lights, and converting to electric signals and digitally converting a Stokes light and an anti-Stokes light simultane ously. SOLUTION: An oscillation wavelength of light sources 2a, 2b is λ0. The light sources generate pulse lights simultaneously by a single trigger 1. The pulse lights are passed through an optical branching filter 3 and input to a sensor optical fiber 11. An intensity of a back scattering light from the sensor optical fiber 11, namely, a Stokes light λs and an anti-Stokes light λas can be increased by enhancing an intensity of the pulse lights sufficiently. The lights are converted to electric signals at photodetectors 4, 5 and further digitally converted at A/D converters 6, 7 respectively. A data processor 8 simultaneously detects the digitally converted signals and calculates a temperature.  Since the intensity of the anti-Stokes light λas and Stokes light λs is increased, an SN to a noise level is improved and position-resolving performance is also improved.
